Greg Miller from the Washington Post writes on a recently released Senate report on the CIA’s enhanced interrogation techniques. Earlier in 2012 the Justice Department closed investigations over alleged abuses at the hands of the CIA, ending the prospect that agents will face criminal charges.

I wonder if there will one day be a similar report on the efficacy of drone strikes?

After a contentious closed-door vote, the Senate intelligence committee approved a long-awaited report Thursday concluding that harsh interrogation measures used by the CIA did not produce significant intelligence breakthroughs, officials said.

The 6,000-page document, which was not released to the public, was adopted by Democrats over the objections of most of the committee’s Republicans.

The report is the most detailed independent examination to date of the agency’s efforts to “break” dozens of detainees through physical and psychological duress, a period of CIA history that has become a source of renewed controversy because of torture scenes in a forthcoming Hollywood film, “Zero Dark Thirty.”

Officials familiar with the report said it makes a detailed case that subjecting prisoners to ­“enhanced” interrogation techniques did not help the CIA find Osama bin Laden and often were counterproductive in the broader campaign against al-Qaeda.
